How to control how long an object is recoverable in the AD Recycle Bin.

The active Directory Recycle Bin is your tool to recover a deleted object, and all it’s associated properties. An object is only recoverable for a certain length of time. You can configure this period of time to meet your organizations needs. First you need to turn on the AD Recycle Bin. The command below will do this:

Enable-ADOptionalFeature –Identity ‘CN=Recycle Bin Feature,CN=Optional Features,CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=Your forest root domain’ –Scope ForestOrConfigurationSet –Target ‘Your forest root domain’

Once you have turned it on, any object delete after this point can be recovered. By default, the retention period is 180 days. To control the amount of time that you have to execute the recovery:

Set-ADObject -Identity "CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=" -Partition "CN=Configuration,DC=" -Replace:@{"msDS-DeletedObjectLifetime" = }

On a final note, remember that this is a Windows Server 2008 R2 feature.

Where did a User’s Account Get Locked Out?

Updated: May 15, 2015 When this article was originally published, two extra carriage returns were add causing the code to malfunction. The code below is correct. My client for this week’s PowerShell class had a really interesting question. They needed to know where an account is being locked out at. OK, interesting. Apparently users hop around clients and forget to log off, leading to eventual lock out of their accounts. The accounts can be unlocked, but are then relocked after Active Directory replication. This problem is solved in two parts. The first one is to modify the event auditing on the network. The second part is resolved with PowerShell. The first part involves creating a group policy that will encompass your Domain Controllers. In this GPO, make these changes.
